Corrupted Database

[ColMac]

Hi I opened Calibre this morning to be told there was an update.

So 9.16 was installed. (I didn't install any new plugins today). On opening, it told me my database was corrupted and so I created a new empty one which seems fine.

I have 3 catalogs in total, and it tells me all are corrupted.

Malwarebytes tells me I'm virus clear, CrystalDiskInfo tells me my disk is in good condition.

Seems odd that I have corruption on all 3 at the same time. One hasn't even been opened since I believe Feb this year, I believe the other two may not have been accessed for approx 3 weeks.

I havent looked at my backups yet, but due to the passage of time, they may all be the current version.

Are there any hints/suggestions as to the problem from the attached code?

I did try repairs, but they failed!

Corrupted database

The library database at Library\FamiIy appears to be
corrupted. Do you want calibre to try and rebuild it automatically? The
rebuild may not be completely successful.

I have just checked my Backup of my main Catalog and it loads apparently perfectly

Have you rebuilt the databases?
